Abstract
1,208,740. Valves. MYSON HEAT EXCHANGERS Ltd. 14 Nov., 1968 [14 Nov., 1967], No. 51777/67. Heading F2V. In a valve having a housing 11 of generally square external configuration and a straight flow passage 17 extending between externally threaded ports 15, 16, there is formed an annular blind bore 18 which extends transversely to passage 17 and accommodates a rotatable spindle 20. The spindle is formed with a bore 26 which may be moved into or out of alignment with passage 17, is engaged by two P.T.F.E. seals 33, 34, each of which engages at its free end a ring seal 32, 36, respectively, with ring seal 36 being further engaged by an adjustable nut 35, and is retained within the housing 11 by deformation of the housing, e.g., by peening over a housing annular lip 28 so that the lip engages a cover-plate 27 resting on a spindle shoulder 21. In a modification, Figs. 5 and 6, not shown, the externally threaded ports (42, 43) are disposed at right angles to each other and the spindle is acted upon by two P.T.F.E. seals (34<SP>1</SP>) each of which is subjected, with the interposition of a ring seal, to the control of an adjustable nut (35<SP>1</SP>).
